74HC7403 - Philips

74HC7403 4-Bit x 64-word FIFO register

The 74HC/HCT7403 are high-speed Si-gate CMOS devices. They are specified in compliance with JEDEC standard no.7A. The “7403” is an expandable, First-In First-Out (FIFO) memory organized as 64 words by 4 bits. A guaranteed 15 MHz data-rate makes it ideal for high-speed applications. A higher data-rate can be obtained in applications where the status flags are.

Features

• Synchronous or asynchronous operation
• 3-state outputs
• 30 MHz (typical) shift-in and shift-out rates
• Readily expandable in word and bit dimensions
• Pinning arranged for easy board layout: input pins directly opposite output pins
• Output capability: driver (8 mA)
• ICC category: LSI. APPLICATIONS
• High-speed disc or tape controller
• Communications buffer. GENERAL DESCRIPTION The 74HC/HCT7403 are high-speed Si-gate CMOS devices. They are specified in compliance with JEDEC standard no.7A. The “7403” is an expandable, First-In First-Out (FIFO) memory organized as 64 words by 4 bits. A g.
